Hi all.

How do i let each thread share same DBI handle($dbh)?

Is that impossible? I need your help.

#!/usr/bin/perl -w

use threads;
use threads::shared;
use DBI;
use DBD::mysql;

my $dbh = DBI->connect("dbi:mysql:host=xxx.xxx.xxx.xxx;database=xxx", 
+"xxx","xxx");
share($dbh);            # its not work!!

my $threads_cnt = 4;

my @threads;
for (my $i = 0;$i < $threads_cnt ;$i++) {
    $threads[$i] = threads->create(\&test);
}

for (my $i = 0;$i < $threads_cnt ;$i++) {
    $threads[$i]->detach;
}

while(1) {sleep;}
exit;

sub test()
{
    my $tid = threads->self->tid;

    my $cursor = $dbh->prepare("select * from users");        # each t
+hread can't share $dbh..
    $cursor->execute();
    my $result = $cursor->fetchrow();
    $cursor->finish();

    $dbh->disconnect;

    open (FILE, ">files/test_$tid.txt");
    print FILE $result;
    close (FILE);
}
